Description

Insecticidal composition and application thereof Technical Field The invention belongs to the technical field of pesticides, and particularly relates to an insecticidal composition and application thereof. Background Cyromazine specific triazine insect growth regulators. Has strong systemic conduction effect, and has strong inhibition effect on the development of larvae of diptera insects (such as liriomyza sativae, gall midge, aphid eating and root maggot) and part of coleoptera insect larvae. Can make the larva become morphologically distorted and not normally pupated. Cyromazine is an insect growth regulator with low toxicity for interfering or inhibiting the growth process of pests, has the advantages of good penetration and systemic property, and the like, but also has the defects of slow insecticidal speed and high price. Diafenthiuron is a novel thiourea high-efficiency insecticidal and acaricidal agent, has the effects of contact poisoning, stomach poisoning, internal absorption and fumigation, and has a certain egg killing effect. Chitin synthesis can be inhibited by interfering with the energy metabolism of the nervous system, disrupting the essential functions of the nervous system. The pests are paralyzed and then dead after the pesticide is applied in the field, so that the initial effect is slow, the pesticide takes effect 3 days after the pesticide is applied, and the pesticide effect reaches the peak period of pesticide effect 5 days after the pesticide is applied. Triflupirtine, also known as pyridalyl, is a highly effective, low toxicity pesticide developed by Sumitomo chemical company. Is mainly used for preventing and controlling lepidoptera pest larvae. In the process of intensive research of the compound of the formula (I) and the compounding process of cyromazine, diafenthiuron and trifluoperal, the inventor surprisingly finds that the compound of the formula (I) and any one of cyromazine, diafenthiuron and trifluoperal are compounded, and has remarkable synergism on various agricultural and forestry pests, especially lepidoptera and diptera pests, in a certain compounding proportion range, and the invention is completed through further research.
